What is an assumption of PERT?

A. A project will always be behind schedule, if left uncorrected. Cost of project will always be more than the estimated cost, if no timely corrections are taken. A project can be subdivided into a set of predictable, independent activities.

Which of the following is an assumption made by the Critical Path Method?

Critical path analysis relies on a few simple assumptions: Projects are made up of tasks. Tasks are combined to form a timeline. Within this timeline, tasks are either concurrent (can occur simultaneously) or sequential (one task cannot begin until the predecessor [superior task] is complete).

Which of the following is one of the assumptions of PRT?

Which of the following is one of the assumptions of PERT? Total project completion time follows a normal probability distribution. Activity times are dependent and correlated.

What is the CPM method of project network What are its characteristics?

The critical path method is a system for organizing all of the tasks that need to be done to complete a project and estimating how long the project will take. CPM analysis pinpoints the most time-sensitive activities in a project as well as those with some scheduling flexibility, or slack.

Which are the features of PERT and CPM?

PERT vs CPM
Abbreviation
PERT – Project Evaluation and Review Technique CPM – Critical Path Method
PERT – PERT is a popular project management technique that is applicable when the time required to finish a project is not certain CPM – CPM is a statistical algorithm which has a certain start and end time for a project

What is the difference between PERT and CPM?

The main difference between PERT and CPM is that PERT stands for Program Evaluation and Review Technique, and CPM stands for Critical Path Method. PERT manages unpredictable activities, whereas CPM manages predictable activities. PERT is related to the events, but CPM is related to the activities.

How many times estimates are made in CPM?

Estimate Activity Completion Time

The time required to complete each activity can be estimated using past experience or the estimates of knowledgeable persons. CPM is a deterministic model that does not take into account variation in the completion time, so only one number is used for an activity’s time estimate.

Which of the following is a basic assumption of PERT quizlet?

Which of the following is a basic assumption of PERT? No activity in the network must be repeated. The critical path for the network activities shown below is A-D-E with duration 13.

What is total float in CPM?

Total Float is the amount of time that an activity can be delayed from its early start date without delaying the project finish date. Free Float is the amount of time that an activity can be delayed without delaying the early start date of any successor activity.

What is crashing a project?

Project crashing in project management is a method used to speed up a project’s timeline by adding additional resources without changing the scope of the project.

What is dummy activity in CPM?

A dummy activity is a simulated activity of sorts, one that is of a zero duration and is created for the sole purpose of demonstrating a specific relationship and path of action on the arrow diagramming method.

What is critical path in PM?

A critical path in project management is the longest sequence of activities that must be finished on time in order for the entire project to be complete. … CPM revolves around discovering the most important tasks in the project timeline, identifying task dependencies, and calculating task durations.

What are the types of float?

There are two types of float in project management, free float (FF) and total float (TF).
  • Free float is the amount of time that a task can be delayed without impacting the subsequent task.
  • Total float is the amount of time a task or a project can be delayed without impacting the overall project completion time.

What is independent float in CPM?

Independent float is the time by which starting or finishing of an activity can be delayed without affecting the total float of its proceeding and succeeding activity. It does not affect start of succeeding activity i.e. following activity.

What is float scheduling?

Put simply, project management float is the amount of time a given task can be delayed without causing a delay in the entire project. … Total float is the amount of time a task can move without impacting the final project delivery date.

What is total float?

Total Float is the amount of time by which you can delay an activity from its early start date without delaying the project finish date.

What is CPM chart?

Create a CPM chart to visualize and scope project tasks

The critical path method is a standard technique used to identify and schedule the sequence of critical tasks and events that determine the duration and completion of a project.

What is PM float?

In project management, float or slack is the amount of time that a task in a project network can be delayed without causing a delay to: subsequent tasks (“free float”) project completion date (“total float”).

What are the three types of float?

Types of Float
  • Total Float or Float.
  • Free Float.
  • Project Float.
  • Interfering Float (INTF)
  • Independent Float (INDF)
